The basic operation method of hydraulic shears machine and the problem of shear blades
Some basic operation methods of hydraulic shears machine are as follows:
- How to replace the pipe seals of hydraulic shearsmachine? Put the tool holder of the hydraulic shearing machine at the bottom dead center, then cut off the power of the machine tool, loosen the pipe of the part where the oil is leaking, take out the broken seal, apply grease to the joint groove, and then seal the new one Put the parts into the groove, tighten the tube, and finally reset the hydraulic shear oil show.
- Does the hydraulic shearing machine produce working pressure? 1. Check whether the positive and negative rotations of the shearing machine motor and oil pump are correct. 2. Clean the valve body of the safety relief valve of the shearing machine. 3. Clean the two-position four-way solenoid valve of the hydraulic system of the shearing machine.
- The return speed of the tool post of the hydraulic shearing machine is slow. 1. Refill the plywood with engine oil. 2. Check the joints of the shearing machine for signs of oil leakage and oil leakage.
Four, hydraulic shear blade turning and gap adjustment 1, hydraulic shear blade turning. Adjust the upper blade holder to zero with the button with reduced shear angle, then remove the table guide, loosen the screws that fix the lower blade, then loosen the screws that fix the lower blade, take out the upper blade one by one, and then flip each blade , Install the lower blade in turn. Confirm that the connector between the blades is smooth and flat, and finally fix all blade screws and install the guide plate.
Just go up.
- Gap adjustment of hydraulic shears. Using the characteristics of larger shear angle and smaller two buttons, the upper edge of the machine tool can be overlapped to three to five millimeters from the two ends of the lower edge to adjust the minimum gap value. After adjustment, after filling the machine with oil once, the upper tool post will automatically reset, press the key.
Causes and solutions of the failure of the shear blade
The reasons for the failure of the shear blade are usually as follows: 1. If the shear angle of the shear can be adjusted, the shear angle may also be adjusted incorrectly. 2. The main pressure valve is adjusted incorrectly, and the system pressure is too low. 3. Tandem cylinders need to be filled with oil. 4. The sealing ring in the series cylinder leaks.
Before using the shearing machine knife, check whether the blade can rotate reliably, and then rotate the wheel by hand, check whether the rotation direction of the wheel is the same as the direction indicated by the mechanical arrow, whether there is collision in the crushing chamber, the power machine and the shearing machine tool Whether the lubrication is good or not, pay attention to the movement of the shearing machine knife. If you find abnormal sound, vibration, excessive temperature of the bearing and machine body, spraying materials to the outside, etc., you must stop the inspection immediately.
The shearing machine must be idling for two minutes after starting to make the motor start normally. Please try to maintain uniformity during the input process, and do not cause excessive equipment load due to centralized input. The quality of the shearing machine’s knives depends on his knives. The quality of the blade depends on its material. What material is used to make the wood shears knife depends on the material of the product that needs to be crushed.
There are usually three types of blades: machining, multi-blade structure, and spiral surface structure. These three supply methods include oblique and flat supply. Long logs are generally supplied with a flat mouth, and short logs and slabs are supplied with an oblique mouth.
In addition, check whether there are scrap metals and other hard materials in the necessary shearing machine materials. If any, in order to avoid the collapse of the shear blade, it must be cleaned. In addition, check whether there are any blades that are about to fall off in the blade group of the wood shears every day before leaving get off work. If there are any, they must be replaced immediately. The blade is damaged. Once it falls into the material box, a set of blades will be discarded. In severe cases, it will cause death and injury to the operator.
The above is the introduction to the reasons and solutions of the shear blade failure, thank you for reading.
